If Mike does his mathematics homework today, the probability that he will do it tomorrow is 0.8. The probability that he will do
harina [27]

Answer:

d. 14:11

Step-by-step explanation:

There is a 7 in 10 chance that Mike does his homework today and a 8 in 10 chance he will do it tomorrow,  the probability that he will do it both today and tomorrow is:

P = \frac{7}{10}* \frac{8}{10}\\P=\frac{56}{100}=0.56

The odds are the probability that an event occurs over the probability that it does not occur:

Odds = \frac{0.56}{1-0.56}=\frac{56}{44}=\frac{14}{11}

The odds that he will do it both today and tomorrow are 14:11.

The owner of a manufacturing plant employs eighty people. As part of their personnel file, she asked each one to record to the n
Mashcka [7]

Answer:

The variance of the given data is 106.9667

Step-by-step explanation:

The variance, S² of a sample is given by the expression;

S^2 = \dfrac{\sum \left (x_{i}-\bar{x}  \right )^{2}}{n-1}

Where:

x_{i} = One of the observations

\bar{x} = The mean of the observations

n = Number in the sample = 6

The mean = Σx_{i}/n = (26  + 32 + 29  + 16  + 45  + 19 )/6 = 167/6 = 27.833

Therefore, we have;

S² = ((26 - 27.833)²+(32 - 27.833)²+(29 - 27.833)²+(16 - 27.833)²+(45 - 27.833)²+(19 - 27.833)²)/(6 - 1) = 106.9667.
